A simple explanation of gluten, why the gluten-free diet is trending, and how this protein affects people's health, from celiac disease to sensitivity.
Gluten is a family of proteins naturally found in grains like wheat, barley, and rye. It functions like a glue, giving dough its elasticity and providing the characteristic chewy texture in foods such as bread and pasta. Because of these unique properties, it is often added to processed foods to improve texture and help them maintain their shape. While it has been a component of the human diet for centuries, it has become a major topic in nutrition due to its effects on a growing number of individuals.
The gluten-free movement has gained significant momentum due to increased public awareness and better diagnosis of gluten-related disorders like celiac disease. The trend is also amplified by media, celebrities, and wellness influencers promoting gluten-free diets as a path to improved health and weight loss. This has created a massive market for gluten-free products, making them more accessible than ever. As a result, many people without a specific medical condition are choosing to eliminate gluten from their diets, contributing to the trend's growth.
For the majority of people, gluten is completely harmless. However, for those with celiac disease, consuming gluten triggers an autoimmune response that damages the small intestine, leading to bloating, diarrhea, fatigue, and nutrient malabsorption. Some individuals have non-celiac gluten sensitivity, causing similar symptoms without the intestinal damage. A smaller group may have a wheat allergy, a distinct allergic reaction. For those who can tolerate it, whole grains containing gluten are a source of important nutrients and can act as a prebiotic, supporting healthy gut bacteria.
